The Scilly naval disaster of 1707 was the loss of four warships of a Royal Navy fleet off the Isles of Scilly in severe weather on 22 October 1707. More than 1,400 sailors aboard the wrecked vessels lost their lives, making the incident one of the worst maritime disasters in the history of the British Isles. The main cause of the disaster was the navigators' inability to accurately calculate their positions.[1]

HMS Romney, a 50-gun fourth-rate ship of the line commanded by Captain William Coney,[2] hit Bishop Rock and went down with all but one of her crew. The sole survivor from the three largest ships was George Lawrence, who had worked as a butcher before joining the crew of Romney as quartermaster.[10][11]

HMS Firebrand, a fireship commanded by Captain Francis Percy, struck the Outer Gilstone Rock like Association, but unlike the flagship she was lifted off by a wave. Percy managed to steer his badly damaged ship along the southern side of the Western Rocks[9] between St Agnes and Annet, but she foundered in Smith Sound, sinking close to Menglow Rock and losing 28 of her crew of 40.[10]

The exact number of officers, sailors and marines who were killed in the sinking of the four ships is unknown. Statements vary between 1,400[12] and over 2,000,[9] making it one of the greatest maritime disasters in British history. For days afterwards, bodies continued to wash onto the shores of the isles along with the wreckage of the warships[13] and personal effects. Many dead sailors from the wrecks were buried on the island of St Agnes.[14] Admiral Shovell's body, along with those of his two Narborough stepsons and his flag-captain, Edmund Loades, washed up on Porthellick Cove on St Mary's the following day, almost seven miles (11 km) from where the Association was wrecked. A small memorial was later erected at this site. The circumstances under which the admiral's remains were found gave rise to stories (see below). Shovell was temporarily buried on the beach on St Mary's (see image).[15] By order of Queen Anne his body was later exhumed, embalmed and taken to London where he was interred in Westminster Abbey.[9] His large marble monument in the south choir aisle was sculpted by Grinling Gibbons.[8] There is a memorial depicting the sinking of the Association in the church at the Narboroughs' home of Knowlton near Dover.

One myth associated with the disaster alleges that a common sailor on the flagship tried to warn Shovell that the fleet was off course but the Admiral had him hanged at the yardarm for inciting mutiny. The story first appeared in the Scilly Isles in 1780 with the common sailor being a Scilly native who recognised the waters as being close to home but was punished for warning the Admiral. It was claimed that grass will never grow on the grave where Shovell was first buried at Porthellick Cove because of his tyrannical act against an islander. The myth was embellished in the 19th century when the punishment became instant execution and the sailor's knowledge of the fleet's position was attributed to superior navigational skills instead of local knowledge. While it is possible that a sailor may have debated the vessel's location and feared for its fate, such debates were common upon entering the English Channel, as noted by Samuel Pepys in 1684. Naval historians have repeatedly discredited the story, noting the lack of any evidence in contemporary documents, its fanciful stock conventions and dubious origins.[16] However the myth was revived in 1997 when author Dava Sobel presented it as an unqualified truth in her book Longitude.[17]

Another story that is often told is that Shovell was alive, at least barely, when he reached the shore of Scilly at Porthellick Cove, but was murdered by a woman for the sake of his priceless emerald ring, which had been given to him by a close friend, Captain James Lord Dursley. At that time, the Scillies had a wild and lawless reputation.[11] According to a letter written in 1709 by Edmund Herbert, who was sent to Scilly by Shovell's family to help locate and recover items belonging to the admiral, Sir Cloudesley's body was first found by two women "stript of his shirt" and "his ring was also lost off his hand, which however left ye impression on his finger." Shovell's widow, Elizabeth, had offered a large reward for the recovery of any family property.[11] It is claimed that the murder only came to light some thirty years later when the woman, on her deathbed, produced the stolen ring and confessed to a clergyman that she had killed the admiral.[4] The clergyman supposedly sent it back to the 3rd Earl of Berkeley,[18] although several historians doubt the murder legend as there is no record of the ring's return and the story stems from a romantic and unverifiable "deathbed confession".[19]

The disastrous wrecking of a Royal Navy fleet in home waters brought great consternation to the nation. The main cause of the catastrophe has often been portrayed as the navigators' inability to accurately calculate their longitude.[4] Clearly, something better than dead reckoning was needed to find the way in dangerous waters. As transoceanic travel grew in significance, so did the importance of reliable navigation. This eventually led to the Longitude Act in 1714, which established the Board of Longitude and offered large financial rewards for anyone who could find a method of determining longitude accurately at sea.[4] After many years, the consequence of the Act was that accurate marine chronometers were produced and the lunar distance method was developed, both of which became used throughout the world for navigation at sea.

However, it is not certain that the navigational error leading to the wrecking of Admiral Shovell's fleet was purely one of longitude, and no contemporary discussions are known that appear to have related the disaster to either navigation or longitude.[20] The Royal Navy conducted a court-martial of the officers of the Firebrand, who were acquitted, but no officers survived from the four lost ships, so no other courts-martial took place. The Navy also conducted a survey of compasses from the surviving ships and of those at Chatham and Portsmouth dockyards, following comments from Sir William Jumper, captain of the Lenox, that errors in the compasses had caused the navigational error. This showed what a poor state many were in; at Portmsouth, for example, only four of the 112 wooden cased compasses from nine of the returning vessels were found to be serviceable.[21][22]

William May points out that the position of the Isles of Scilly themselves was not known accurately in either longitude or latitude. In addition, his analysis of the 40 extant logbooks from the 21 ships in the fleet do not show the error in longitude to be a significant factor compared to latitude.[23]

The ships of Sir Cloudesley Shovell's fleet lay undisturbed on the seabed for over 250 years,[10] despite several salvage attempts in pursuit of the flagship's cargo of valuable coins, spoils of war from several battles, weapons, and personal effects.[24] In June 1967, the Royal Navy minesweeperHMS Puttenham, equipped with twelve divers under the command of Engineer-Lieutenant Roy Graham, sailed to the Isles of Scilly and dropped anchor off Gilstone Ledge, just to the south-east of Bishop Rock[25] and close to the Western Rocks. The year before, Graham and other specialists from the Naval Air Command Sub Aqua Club had dived in this area on a first attempt to find the Association. He recalled some years later: "The weather was so bad, all we achieved was the sight of a blur of seaweed, seals and white water as we were swept through the Gilstone Reef and fortunately out the other side."[10][26] On their second attempt in summer 1967, using the minesweeper and supported by the Royal Navy Auxiliary Service, Graham and his men finally managed to locate the remains of Admiral Shovell's flagship on the Gilstone Ledge.[26] Parts of the wreck are in 10 m (30 ft) while others can be found at between 30 m (90 ft) and 40 m (120 ft) as the sea floor falls away from the reef.[27] The divers first discovered a cannon, and on the third dive, silver and gold coins were spotted underneath that cannon.[26] The Ministry of Defence initially suppressed news of the discovery for fear of attracting treasure hunters, but word was soon out and excited huge national interest.[25] As the Isles of Scilly are traditionally administered as part of the Duchy of Cornwall, the Duke of Cornwall also has right of wreck on all ships wrecked on the Scilly archipelago. More than 2,000 coins and other artefacts were finally recovered from the wreck site and auctioned by Sotheby's in July 1969.[28] A further sale at Sotheby's in January 1970, by order of the Isles of Scilly Wrecks Receiver, made £10,175. Among the goods sold was Shovell's chamber pot for £270. A battered dining plate, which had been discovered during a dive in 1968, brought £2,100.[29] The rediscovery of the Association by naval divers and the finding of so many historical artefacts in her wreck also led to more government legislation, notably the Protection of Wrecks Act 1973, passed in an attempt to preserve British historic wreck sites as part of the maritime heritage.[14]

The wreck of Firebrand was discovered in 1982, and several items were recovered, including guns and anchors, a wooden nocturne (for determining the time at night), a bell and carved cherubs.[30]

Today photos of the original diving expedition are on display at the Old Wesleyan Chapel in St. Mary's, of the team leader Lt Graham and a naval doctor examining human bones from the wreck of the Association, alongside the ship's bell of the Firebrand with "1692" engraved on it, and many more artefacts.[25] In 2007, the three-hundredth anniversary of the disaster and its consequences were commemorated on the Isles of Scilly with a series of special events, organised by the Council of the Isles of Scilly in partnership with the local AONB office, English Heritage, the Isles of Scilly Museum and Natural England.[31]
